Question
There is a substantial amount of discussion regarding the environmental impacts associated with the livestock industry. Increasing human population results in an expansion of the cattle rising industry in the US and likely worldwide. In orderto gain an insight into the impacts of the industry you should visit the website www.eiolca net and from the US2002 producer database choose the industrial sector 'Agricultural, Livestock, Forestry and Fisheries' and the subsector 'Cattle Ranching and Farming' and address the impacts of the following scenario. The total US beef production 2004 was 24.6 billion pounds at a farm to wholesale price of $1.75 per pound. In the year 2016 the total production was 24.96 billion pounds at a farm to wholesale price of $2.56 per pound. Run the EIO-LCA model and then answer the following questions: ) What are the top 5 sectors benefiting from this increase in beef production (economic activity)? b) Which are the GHGs emissions associated to this increase in industrial/economic output of the sector? How about water withdrawals? c) d) What should the sector do if they set a goal to reduce GHG emissions? e) Shortly summarize and comment your findings (one paragraph max) Assume that you can use the provided per pound price values of beef without correction to run the 2002 model.

d. The secor should reduce burning fossil fuels. Only then, the greenhouse gases emission reduces.
e. due to the increse in the release of the toxic substances, the effects are the realease of carcinogens, non-carcinogens, the depletion of ozone layer, global warming, completion of non-renewable energy, mineral extraction and so on. Thecombustion of fossil fuels should be reduced and then the greenhouse gases emission reduces.
